The influence of incubation temperature on offspring traits varies across northern and southern populations of the American alligator ().

Maternal provisioning and the developmental environment are fundamental determinants of offspring traits, particularly in oviparous species. However, the extent to which embryonic responses to these factors differ across populations to drive phenotypic variation is not well understood. Here, we examine the contributions of maternal provisioning and incubation temperature to hatchling morphological and metabolic traits across four populations of the American alligator (), encompassing a large portion of the species' latitudinal range.

Long-term outcomes of the conformable TAG thoracic endoprosthesis in a prospective multicenter trial.

Background: The Gore conformable TAG thoracic endoprosthesis (CTAG) was engineered to enhance conformability in the thoracic aorta and has demonstrated greater deployment accuracy and wall apposition than the original TAG device. The Food and Drug Administration approved the CTAG in 2011 based on the 1-year results of the pivotal trial for the CTAG device. In the present report, we have documented the outcomes for those patients through 5 years.

Hemostasis biomarkers and incident cognitive impairment: the REGARDS study.

Unlabelled: Essentials Cognitive disorders are increasing and vascular risk factors play a role in this. We performed a nested case control study of hemostasis biomarkers and cognitive impairment (CI). Higher baseline fibrinogen, factor VIII and D-dimer were related to incident CI over 3.

Correlates of Incident Cognitive Impairment in the REasons for Geographic and Racial Differences in Stroke (REGARDS) Study.

Objective: To identify approximately 500 cases of incident cognitive impairment (ICI) in a large, national sample adapting an existing cognitive test-based case definition and to examine relationships of vascular risk factors with ICI.

Method: Participants were from the REGARDS study, a national sample of 30,239 African-American and White Americans. Participants included in this analysis had normal cognitive screening and no history of stroke at baseline, and at least one follow-up cognitive assessment with a three-test battery (TTB).

Dietary contributors to glycemic load in the REasons for Geographic and Racial Differences in Stroke study.

Objective: High dietary glycemic load (GL) has been associated with an increased risk for chronic diseases, including type 2 diabetes, coronary heart disease, and selected cancers. The aim of this study was to identify the main food and food group contributors to dietary GL in a representative sample of US adults to inform future interventions.

Methods: Participants were from the REGARDS (REasons for Geographic and Racial Differences in Stroke) study, a longitudinal cohort of 30 239 community-dwelling black and white women and men ages ≥45 y from throughout the United States.
